Ireland is forecast to experience warmer conditions over the weekend, with temperatures rising to around 23C in many areas. RTE reports that the change is driven by high pressure moving in from the south of Europe. The high-pressure influence is expected to support milder, drier weather across the country, leading to a noticeable improvement in temperatures compared with recent conditions. The forecast points to broadly nationwide warmth rather than a limited regional effect, indicating that multiple counties are likely to see similar temperature highs. While the reports focus on the upper temperature range, they attribute the shift primarily to the prevailing synoptic weather pattern associated with the south-European high-pressure system. Overall, the weekend weather outlook is one of higher temperatures under stable conditions, with 23C cited as the top figure for the period.
